There will be 5 Big Ten teams in action in the second round of the NCAA Tournament on Sunday — and one former Big Ten coach.

It’s been 16 years now, but there is presumably little love lost between Illinois fans and Houston coach Kelvin Sampson.

Back when it was considered controversial to flip recruits, Sampson made an impact in his first year as Indiana’s head coach by getting Indianapolis native Eric Gordon to renege his commitment to Illinois and sign with Indiana.

Gordon was booed mercilessly by Illinois fans when he and the Hoosiers visited Champaign in February 2008 but ended up getting the last laugh with a late 3 that sent the game to overtime. Gordon, Sampson and the Hoosiers won that game to complete the season sweep.

Illinois fans got the next laugh after that, though.

Exactly 2 weeks later, Sampson was forced to resign from his position as a result of NCAA allegations for impermissibly sending text messages to recruits.

On Sunday, Sampson will face the Fighting Illini for the first time since that 2008 game in Champaign.

South Region

No. 4 Illinois vs. No. 5 Houston

When: 12:10 p.m. ET

Where: Pittsburgh

How Illinois got here: Alfonso Plummer hit a pair of free throws with 12 seconds left to lift the Illini to a 54-53 win over No. 13 Chattanooga, which led for all but 35 seconds of the game.

How Houston got here: The Cougars shot a blistering 64% from the field, which was more than enough to keep 12th-seeded UAB at bay, 82-68.

Keys to the game

If Houston shoots better than 60% again, you can obviously put this one in the books. But that’s unlikely to happen against Illinois’ defense. However, the Cougars are the nation’s 4th-best offensive rebounders. (You just wouldn’t know it from the UAB game because they never missed.)

Illinois must limit the Coogs to 1-shot possessions — and make sure the shots don’t go in.

Prediction: Houston 66, Illinois 63

It is very, very difficult to buy into the Illini right now after the way they struggled against Chattanooga.

Maybe it was a wakeup call, but Illinois was already going to have to play its best game to beat a Houston team that probably should be a 3-seed. We haven’t seen that caliber of performance from the Illini since they clobbered Indiana back on Feb. 5.

No. 7 Ohio State vs. No. 2 Villanova

When: 2:40 p.m.

Where: Pittsburgh

How Ohio State got here: Loyola Chicago had its worst shooting performance in 5 years, and the Buckeyes moved on with a 54-41 win over the Ramblers.

How Villanova got here: The Wildcats used their balance as 5 players scored in double figures in an 80-60 win over Delaware.

Keys to the game

Keep the Wildcats off of the free-throw line. The Wildcats are the nation’s top team at the charity stripe, hitting 82.5% of their free throws.

Prediction: Villanova 75, Ohio State 66

Loyola was able to create plenty of open-shot opportunities against Ohio State’s defense. The Ramblers just couldn’t hit the broad side of a barn, shooting 26.7%. Villanova will create the same shot chances, and figures to be a lot more accurate in the process.

West Region

No. 7 Michigan State vs. No. 2 Duke

When: 5:15 p.m.

Where: Greenville, S.C.

How Michigan State got here: Joey Hauser matched his career-high with 27 points, and the Spartans held off a game Davidson squad for a 74-73 win.

How Duke got here: The Blue Devils had 21 assists on 30 baskets, cruising to a 78-61 win over Cal State Fullerton.

Keys to the game

The good news for Michigan State is the Blue Devils are 303rd nationally in forcing turnovers, so they’re unlikely to exploit the Spartans’ biggest weakness. But Duke is tough to score on inside, so the Spartans will need to be blistering behind the arc.

Prediction: Duke 79, Michigan State 71

It would be fitting for Tom Izzo to be the coach who ended Mike Krzyzweski’s career. Sort of a Highlander-type scenario, if you will.

But it’s probably going to take a better defense than Michigan State’s to derail Duke.

Midwest Region

No. 3 Wisconsin vs. No. 11 Iowa State

When: 6:10 p.m.

Where: Milwaukee

How Wisconsin got here: Johnny Davis scored Wisconsin’s final 14 points to rally the Badgers past No. 14 seed Colgate, 67-60.

How Iowa State got here: Tyrese Hunter hit 7 3-pointers, including a game-sealer with 20 seconds left, as the Cyclones staved off a late LSU rally for a 59-54 win.

Keys to the game

Iowa State’s greatest strength is its ability to turn opponents over — the Cyclones are 5th nationally in turnover percentage.

Wisconsin’s greatest strength is ball protection — the Badgers turn it over less than anyone in the country.

This will be decided by which of those strengths wins out.

Prediction: Wisconsin 60, Iowa State 56

Johnny Davis will get his game in gear far earlier than the final 6 minutes, and another practical home crowd will help Wisconsin win.

East Region

No. 3 Purdue vs. No. 6 Texas

When: 8:40 p.m.

Where: Milwaukee

How Purdue got here: Jaden Ivey scored 22 points to lead the Boilermakers past Ivy League champ Yale, 78-56.

How Texas got here: The Longhorns were money from long-range, making their highest percentage of 3s since the season opener to beat Virginia Tech 81-73.

Keys to the game

Purdue has turned the ball over on at least 22% of its possessions in 3 of its 7 losses. According to, Texas’ defense is 14th nationally in forcing turnovers (23.7% of possessions.)

If the Horns hit their season average, they’ll win. If they don’t, expect Purdue to move on.

Prediction: Purdue 72, Texas 67

The Horns’ primary “bigs” are 6-6 Timmy Allen and 6-7 Christian Bishop. Purdue will have the opportunity to dominate inside with Zach Edey. Or if Texas makes Purdue play small, Matt Painter can counter with more Trevion Williams.

As long as the Boilers can play a clean game, they should move on.
